The Worcester Bosch Greenstar 22mm system filter is an essential protective component engineered to actively safeguard modern heating infrastructure against the detrimental effects of suspended debris and black iron oxide sludge. Utilising a highly effective combination of magnetic and non-magnetic filtration technologies, it consistently extracts microscopic particulate matter from the circulating system water. This proactive extraction significantly extends the operational lifespan of the primary heat exchanger and circulator pump, ensuring the heating system maintains its original thermal efficiency over years of continuous service. The compact dimensions allow for discreet integration into highly confined pipework arrangements.
Designed specifically with the heating engineer in mind, this unit features a fully detachable body that dramatically accelerates servicing and powerflushing procedures. It can be installed with complete flexibility, accommodating positions both above and below the boiler, or even remotely depending on spatial constraints. A dedicated one-way valve simplifies the introduction of essential system chemicals, while clear isolation valve indicators visually confirm system status before maintenance begins. An integrated over-tightening prevention mechanism further protects the integrity of the seals during reassembly, making this an incredibly reliable and tradesman-friendly filtration solution.
Q: What types of debris does this filter extract?
A: It utilises dual filtration to capture both magnetic iron oxide sludge and non-magnetic particulates.
Q: Can the filter be installed remotely from the main boiler unit?
A: Yes, it is highly versatile and can be sited over, under, or entirely remote from the boiler.
Q: How are system chemicals added through this device?
A: It incorporates a convenient one-way valve specifically designed for rapid chemical dosing.
Q: Does the unit prevent damage during routine reassembly?
A: It features a specialised over-tightening prevention mechanism to protect internal O-rings and seals.
